/usr fills up quite fast. by overflow I mean that you run out of space
quickly. so for example when installing a lot of programs with apt-get /
fills-up very quickly. when installing programs via make install, it fills up
/ quickly.
I would think a separate /var /tmp /home /usr would make more sense than a
tiny few GB / partition and a HUGE /home partition. True a symbolic link
could help with /tmp, but that seems hacky to me.
regardless,
the default partition scheme needs to change, regardless of whether or not
you use one large / and a swap (which I prefer and ubuntu does this), or
separate partitions..
